As much as Adobe Reader stinks, I really need to use it more than the open source alternatives, mostly because it's the only one that can organize separate documents into tabs under one window, which none of the others I've tried can do. I have to work with multiple pdf documents constantly, and tabs are really the only sane way to do it.

Anyway, I've recently installed Mint 13, and when installing acroread, it didn't ask if I wanted to set it as the default application like it did in older Mint versions. It is not showing up in file.pdf [right click] -> Properties -> Open with tab. It's not listed in Recommended Applications, and it's not showing up in the list when I click "Show other applications". This new nautilus doesn't seem to allow me to enter a custom command like it used to in older Mint versions (Shameful regression there, Gnome!).

I tried just opening it through Adobe Reader, after which it is in the file.pdf [right click] -> Open with list. However, it is still not in the file.pdf [right click] -> Properties -> Open with tab, so I cannot set it as the default application to open the files when I double-click them.

Same here - I've installed Acroread through Synaptic, but can't make it the default application for opening PDFs. As I deal with a lot of PDF portfolios, Acroread is the only option for opening them, so it's a PITA to have Evince as the default app.

In Nautilus, when I look at the "Open With" tab of the properties dialog for any PDF, Acroread is not listed as one of the possible applications to use for opening PDF files.

I had the same issue, but my fix was simple enough - I uninstalled the default document viewer for MATE (atril, which I have no use for), and Adobe Reader automatically became the default viewer when I double-clicked a PDF file.

Goto System Settings>File Associations>Applications. Then scroll down to PDF, and click on it. It will give a preference order on the right. Move the Adobe reader to the top, then press the "apply" button on the lower right. When you start a PDF again, it shoutld default to Adobe Reader! I hope this helped!

@Mik3e - Menu.. Preferences... System Settings (but you probably got that by now).

Everyone - I am stumped on this one. I need to set acroread as the default for handling pdf files. As others have noted, although "Open with Adobe Reader 9" is available as an option when right-clicking a file, it is not in the list of options for adding as the default. I don't seem to have an acroread.desktop file anywhere.

Note that when Jon N talks about System Settings->File Associations, he's probably talking about KDE which has this menu. KDE seems to make it easier to configure default file associations. I commented on this over at viewtopic.php?f=47&t=100362&p=649250#p649250 ("[SOLVED] How to set default programs/applications?").

UPDATE: As I mentioned in the thread cited in the paragraph, Nautilus (I guess) sometimes HIDES FILE EXTENSIONS. So you might not see the .desktop at the end, but it is there, and so to open these .desktop files in /usr/share/applications you need to add the .desktop to the end - ie, gedit acroread.desktop rather than gedit acroread.
